SPECIFICATION forming part of Letters Patent No. 333,334, dated December 29, 1885.

Application filed July 25. 1885. Serial No. 172,693.

To a/ZZ whom, it may concern:

Beit known that I, ROBERT D. PowEL, of Jerseyville, in the county of Jersey and State of Illinois, have invented a new and Improved Dropper for Corn-Planters; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in droppers for corn-planters of that class adapted to drop simultaneously all the seeds plantedin the same hill, my object being to provide a simple and easily-accessible mechanism for actuating the dropper-plate, all the working parts being so located as to be in view of the driver while the machine is in operation.

Wit-h this end in view my invention consists in certain details of construction and cooperative parts explained in the following specification and illustrated in the accompanying drawings, in which- Figure l is a plan view of one of the seedhoppers and the mechanism connected therewith. Fig. 2 is a sectional side view of the same, taken in the line x x, Fig. l, supported upon one of the runners. Fig. 3 is an enlarged elevational view of the mechanism by which the dropper-plate is actuated.

In the drawings, A represents the seedhopper, having the top or cover removed. B is a circular plate provided with four sets of holes, s, located as shown, and exactly corresponding with a similar set of holes, p, in a fixed plate, C, beneath, which, with the hopper, is secured to the runner D. The plate B is secured to the lower part of the vertical spindle a, the lower extremity of which has a bearing in the plate C, (shown at 6,) the upper part of said spindle being journaled in a cross-bar, c, and having secured to its upperl extremity a circular plate, d, provided with four equidistant studs, f, adapted to engage with two pawls, g, pivoted one on each side of a reciprocating bar, h, which may be actuated either by an ordinary hand-lever or a check-rower.

It will be observed by reference to Fig. 2 that the side la of the hopper is not only nearer than the other sides to the spindle c, but is inclined inward at the lower part of the hopper, and that the cover r, which incloses a (No model.)

segment of the plate B, is of glass. The'object of this construction is to enable the driver 5 5 to see that the plate B, when in operation, drops the seed properly, the lower inner edge of the side 7c preventing any seed from passing under the plate 1^, save what is in the holes s.

To limit the stroke or length of travel of the barh, it is provided with stops i, which at each end of the stroke come in contact with the sides of the hopper, as shown in Fig. 3, said stops being so located upon the bar h that the pawls g, acting upon the studs f-one in one direction and the other in the opposite direction-will impart to the plated, and consequently to the lower plate, B, exactly a quarter of a revolution, thus bringing at each end of the stroke a set of holes, s, to coincide with the set p in the fixed plate C below.

Referring to Fig. 1, it will be observed that the pawls g, being placed upon opposite sides of the bar h, and being adapted to act in op- 7 5 posite directions,will, by the reciprocating action of the bar h, impart to the plate d a rotary intermittent motion in the direction indicated by the arrow. By this disposition and arrangement of the actuating mechanism of my dropper the hopper may be filled with corn without offering any obstruction to the working parts, ,save the weight upon the revolving plate B, which, however, is but slight, owing to the small area of the supporting end e of the spindle a, while all the principal working parts are in full view of the operator, and are easily accessible for repairs, &c.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a corn-planter, the combination, with the vertical revolving spindle a, of the plate d, secured to the upper extremity of said spindle and provided with studs f, adapted to engage with pawls g, pivoted directly to the reciprocating bar h, all constructed and adapted for united operation, as and for the purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 24th day of J une, 1885.

ROBERT D. EOWEL.
